ALL DRAWINGS ARE DIAGRAMMATIC IN NATURE, AND ARE INTENDED TO SHOW

THE GENERAL LAYOUT OF SYSTEMS AND EQUIPMENT. THE EXACT LOCATIONS

OF EQUIPMENT AND THE FINAL DUCTWORK LAYOUTS ARE THE

RESPONSIBILITY OF THE CONTRACTOR, AND SHALL BE FIELD-DETERMINED.

COORDINATE WITH THE BUILDING ARCHITECTURE AND STRUCTURE, AND

WITH NEW AND EXISTING MECHANICAL AND ELECTRICAL SYSTEMS. WHERE

THE LAYOUT DIFFERS SIGNIFICANTLY FROM DESIGN, COORDINATE WITH THE

ARCHITECT/ENGINEER. RECORD ALL DIFFERENCES ON RECORD DRAWINGS.

COORDINATE LOCATIONS OF REGISTERS, DIFFUSERS AND GRILLES WITH THE

REFLECTED CEILING PLANS. COORDINATE ANY DISCREPANCIES WITH THE

ARCHITECT/ENGINEER PRIOR TO INSTALLATION.

INSTALL ALL THERMOSTATS/SPACE TEMPERATURE SENSORS AT 48 INCHES

ABOVE FINISHED FLOOR (TO TOP OF SENSOR). WHERE APPLICABLE, ALIGN

WITH LIGHT SWITCHES.

ALL THERMOSTATS AND SENSORS LOCATED ON EXTERIOR WALLS SHALL

HAVE INSULATED BACKPLATES.

WHERE INTERNALLY LINED OR DOUBLE-WALL DUCTWORK IS SHOWN, THE

DIMENSIONS SHOWN INDICATE THE REQUIRED INSIDE FREE AREA

DIMENSIONS.

THE CONTRACTOR SHALL EXAMINE THE CONDITION OF ALL EQUIPMENT PRIOR

TO INSTALLATION. DO NOT INSTALL DAMAGED EQUIPMENT.

WHERE CONNECTING NEW DUCTWORK TO EXISTING, SEAL JOINTS AIRTIGHT

AND REPAIR DAMAGED INSULATION TO MATCH NEW.

WHERE DUCTWORK IS EXPOSED, ROUTE AS HIGH AS PRACTICAL IN THE

SPACE UNLESS INDICATED OTHERWISE.

REFER TO ARCHITECTURAL CODE COMPLIANCE PLANS FOR THE LOCATIONS

OF FIRE/SMOKE RATED ASSEMBLIES.

PAINT VISIBLE INTERIOR SURFACES OF DUCTS AT REGISTERS, GRILLES,

DIFFUSERS AND LOUVERS FLAT BLACK.

WHERE POSSIBLE, INSTALL EQUIPMENT AND DEVICES REQUIRING SERVICE

OR MAINTENANCE IN ACCESSIBLE LOCATIONS. WHERE NOT POSSIBLE,

PROVIDE ACCESS DOORS, SIZED SUITABLY FOR THE REQUIRED PURPOSE.

COORDINATE ACCESS DOOR LOCATIONS AND SIZES WITH THE

ARCHITECT/ENGINEER.

PROVIDE MANUFACTURERS' RECOMMENDED CLEARANCES FOR AIR FLOW,

ELECTRICAL AND MAINTENANCE AROUND EQUIPMENT. WHERE CLEARANCES

ARE ALSO SHOWN ON THE DRAWINGS, PROVIDE THE MORE STRINGENT OF

THE REQUIRED CLEARANCES.

FLEXIBLE DUCTWORK CONNECTIONS TO RIGID DUCTWORK, TO AIR TERMINAL

UNITS AND TO REGISTERS, GRILLES AND DIFFUSERS SHALL BE CLAMPED AND

TAPED. ROUND CONNECTIONS SHALL HAVE VINYL DRAWBANDS AND TAPE.

TAPE SHALL MEET THE REQUIREMENTS OF U.L. 181B-FX.

FLEXIBLE DUCTWORK SHALL NOT BE USED ON RETURN AIR OR EXHAUST AIR

DUCT SYSTEMS EXCEPT WHERE EXPLICITLY SHOWN ON DRAWINGS.

THE OWNER RESERVES THE RIGHT OF FIRST REFUSAL IN OWNERSHIP OF ANY EQUIPMENT

ITEMS AND MATERIALS TO BE REMOVED FROM THE BUILDING AND SITE.

ALL MATERIALS AND EQUIPMENT REMOVED AND NOT SALVAGED OR RE-USED SHALL BECOME

THE PROPERTY OF THE CONTRACTOR, AND SHALL BE REMOVED FROM THE OWNER ’S

PROPERTY AND DISPOSED OF PROPERLY.

THE DRAWINGS ARE DIAGRAMMATIC IN NATURE, AND ARE BASED ON THE REVIEW OF

PREVIOUS DESIGN DRAWINGS (WHERE AVAILABLE) AND ON LIMITED FIELD INVESTIGATION.

THE CONTRACTOR IS RESPONSIBLE TO INVESTIGATE THE BUILDING AND SITE TO DETERMINE

THE FULL EXTENT OF DEMOLITION WORK REQUIRED. THE CONTRACTOR SHALL FIELD-VERIFY

THE ACTUAL LOCATIONS AND SIZES OF EXISTING DUCTWORK, PIPING AND EQUIPMENT.

WHERE DISCREPANCIES BETWEEN THE DRAWINGS AND THE EXISTING CONDITIONS RESULT IN

AN UNCLEAR DEMOLITION SCOPE, COORDINATE WITH THE ARCHITECT/ENGINEER.

WHERE DEMOLITION OF MATERIALS OR EQUIPMENT IS REQUIRED, REMOVE ALL RELATED

SUPPORTS, ACCESSORIES, LOW-VOLTAGE WIRING, PNEUMATIC TUBING AND CONTROLS

(CONCEALED OR EXPOSED). REMOVE WIRING TO THE NEAREST JUNCTION BOX, AND

PNEUMATIC TUBING TO THE NEAREST MAIN. WHERE A PNEUMATIC CONTROL SYSTEM IS TO

REMAIN ACTIVE, CAP AND SEAL TUBING AT MAINS.

ALL PIPING, DUCTWORK AND EQUIPMENT SHOWN CROSS-HATCHED OR BOLD DASHED SHALL

BE REMOVED OR RELOCATED UNLESS OTHERWISE NOTED.

VERIFY LOCATION AND PROTECT EXISTING WORK AND UTILITIES WHICH ARE TO REMAIN IN

PLACE WITH TEMPORARY COVERS, SHORING, BRACING AND SUPPORTS.

ALL MATERIALS AND EQUIPMENT REQUIRING REMOVAL AND REINSTALLATION FOR RE-USE

SHALL BE CAREFULLY REMOVED AND STORED TO PREVENT DAMAGE. THE CONTRACTOR IS

RESPONSIBLE FOR LOSS OF OR DAMAGE TO STORED MATERIALS AND EQUIPMENT.

WHERE ON-SITE STORAGE OF MATERIAL AND EQUIPMENT IS PERMITTED, COORDINATE

STORAGE LOCATION(S) WITH THE OWNER.

PROTECT THE BUILDING STRUCTURE AND FINISHES AND ALL BUILDING SYSTEMS DURING

DEMOLITION. THE CONTRACTOR IS RESPONSIBLE FOR ANY DAMAGES INCURRED AS A RESULT

OF DEMOLITION WORK.

UNLESS ASSIGNED TO ANOTHER TRADE, PATCH AND REPAIR ALL WALL, FLOOR AND CEILING

OPENINGS DUE TO DEMOLITION WHICH ARE NOT TO BE RE-USED. MATCH EXISTING

SURROUNDING CONSTRUCTION, FINISHES, COLORS AND FIRE/SMOKE RATINGS.

UNLESS ASSIGNED TO ANOTHER TRADE, PATCH AND REPAIR ROOF IN A MANNER WHICH WILL

MAINTAIN THE WATER-TIGHT INTEGRITY OF THE ROOF. WHERE A ROOF WARRANTY EXISTS,

PERFORM THE WORK IN A MANNER WHICH WILL MAINTAIN THE WARRANTY.

IF MATERIALS SUSPECTED OF CONTAINING ASBESTOS ARE ENCOUNTERED, NOTIFY THE

OWNER IMMEDIATELY. WHERE REMOVAL OR ENCAPSULATION IS REQUIRED, SUCH WORK

WILL BE PERFORMED BY THE OWNER UNDER A SEPARATE CONTRACT.
